I’m having an issue with my Ngauge w Boost Box. I had my supercharger install done at Evolution Performance back in July, who also did a remote Lund tune and installed the boost box with ngauge. The analog signal on the Ngauge was reading 0 at idle, which I knew wasn’t correct, and brought the car back to Evolution. They ordered a new boost box and installed it yesterday. They did a vacuum test and said all is good. Now, the analog signal is reading -10ish at idle like it should be, and down to -12 when coasting at speed. The issue is I barely get a positive reading when I punch the throttle. The gauge will get down to 0ish and may go as high as +2 to +3, but not higher. Evolution says the Ngauge/Boost box was calibrated when they originally did the install in July.
